To @ZZ whom/vit may con/cern.-

Be it'known that I, WILLIAM T. FLEMING,

' a citizen of the United States, residing at Los Angeles, in the countyof Los Angeles and -State of California7 have invented new and l usefulImprovements in RollerfBea'rings', of which the following is aspecification.

My invention relates to improvementsV in the construction of the rollersof the bearing and the guides therefor and in the'spacer rollers and inthe means for assembling. and

holding'the rollers together; and the object y thereof is to provide arollerbearing in which IIS i f' the bearing and spacer rollers will 'be.evenly held from lateral or twisting movement.

In the' drawings forming a part of 'the application I have illustratedmy invention as applied to an axle and wheel, the box of the wheel onlybeing shown; but my invention is equally applicable to bearings whereone part is rotatablewithin or exterior vto .the other part. Iaccomplish this .object by means of the device described herein andillustrated in the accompanying drawings in whichz- Figure l-is asection taken on line lv-l of Fig. 2. Fig. Z-is a section taken on lineNear each end the axle 5 is provided with annular flanges 6 and 7 whoseperipheries are convex-which form guides and supports for the ends ofthe spacing rollers 8, which rollers are provided with concave grooves 9which straddle the flanges of the axle. These grooves are deep enough toprevent the spacing rollers fromhavingan endwise or lateral movement,but not deep enough to permit the body of the spacing rollers to engagethe axle, and being concaved any wear that they might be subjected towould not affect, or shift their position on the tracks as the concavedgrooves will always seek the highest point.

The annular flanges 6 and 7 are provided on their sides nearest eachother with annu# lar shoulders l0 and 11 between which the bearingrollers 12 are adapted to rotate. .The bearing rollers are of a largerdiameter than the spacing rollers and are adapted to bear against theaxle and the hub 13 of the wheel.

Surrounding the spacing rollers and within .the grooves at the endsthereof lare the hinged assembling or holding rings 1'49, which ringsare convexed on their inner surfaces and engage with the necks of thespacmg -ing means (no t shown) rings are composed of two hinged members,the free ends being detachably secured'to.- get her.A i

In order to' assemble thel spacing rollers-the assembling rings' areopened and the spacing rollers are put in place after which the freeyrollers'within their'grooves.- These Iholding ends ofthe ring aresecured together in any suitable manner. 'After the 'spacing rollershave been placed on' the axle-the bearing rollers are thenput in theirplaces on the axle,'one between-eacli'two spacing rollers and are heldvin'pla'ce by any temporary hold'- The hub 13 isv then pushed on, thevtemporary holding means being removed' before screwing it to .the ldustcapl.

It will'be' observed-that the co'ope'ration' of the concave groovesinthe spacing rollers witlrtheconvex surfaces of the vadjacent faces o ftherings and the track 'flanges-resuits not only in holding'the spacingrollers- .againstiiundu'e' endwise shifting with the leastpossible'fri'ction but also, 'by reason of the centering acti-onresulting from these convex and concave surfaces, to prevent the ringsstriking against the adjacent ends of the load-sustaining rollers thuspermitting the ends of the load-sustaining rollers to be brought closeto the rings and thus utilize the full widthof the bearing portion ofthe shaft or axle structure. v

I-Iaving described my invention .Wh at I claim as new and desire tosecure by Letters Patent is 1. In combination, a shaft structure hav- Iingtwo annular iianges one at each opposite end of its bearing portion,an outer cylindrical member, load-sustaining rollers ex- IOO thesespacing rollers being of greater length A than the load-sustainingrollers andreach having an annular groove near each of its ends whichengages the adjacent one of the flanges on the axle, and two ringsloosely IIO lhung' in the annular grooves .in the spacing rollers, eachol said grooves being concave and the adjacent faces of the flanges andrings being convex.

2. In combi-nation, a shaft structurehaving secured thereto two rigidannular flanges, one at each endof its bearingortion, an outercylindrical member, loa sustaining rollers having contact with the shaftbetween said annular flanges, spacing-rollers intermediate theload-sustaining rollers andeach 4having longitudinal contact with thetwo adax e, and two rings loosely hunginthe annular grooves in thespacing4 rollers beyond the ends of the load-,sustaining rollers.

3. In combination, a shaft structure having Isecured thereto two rigidannular flanges, one 4at each endof its bearing orton, .an

outer cylindrical member, loa sustaining rollers bearing on the 4shaftstructure be- 'go tween said annular flanges, spacing'rollersintermediatethe load-sustaining rol rs and each having longitudinalcontact with the two 4 rollers.

. adj aeent `lo ad-sustaining rollers, these spaeing rollers being ofless diameter than the loadsustaining rollers and having grooves intheir on the shaft structure, whereby they yare freely supported betweenthe shaft structure andthe outer member, and two rings loosely hung inthe annular grooves in the spacing rollers. l

4. In combination, a shaft structure having secured thereto two rigidannular flanges, one at each end of -its bearing ortion, an 'outercylindrical member, load-)sustaining rollers bearing cnthe shaftstructure, spacing rollers intermediate the load-sustaining :rollers andeach. having longitudinal'contact with the two adjacent load-sustainingrollers, these s acing-rollers having grooves in their ends W ich engageover the annular flanges on the shaft structure, whereby' they arefreely supported between the shaft structure and theouter member, andtwo rings loosely hung in the annular 'grooves in the spacing In Witnessthat' VI claim the foregoing I have hereunto subscribed my name this lthday of August, 1906.
